Ivy: binding to [style.opacity] with a value of 0 is broken

🐞 bug report

Affected Package

The issue is caused by package @angular/core

Is this a regression?

Yes, it works in non-ivy.

Description

@Component({
  selector: 'app-test',
  template: `
    <label [style.opacity]="opacity">
      This has an opacity binding, and should not be visible
    </label>

})
export class MyComponent {
  opacity = 0;
}

The 9.0.0-next.10 release is likely to contain a fix for this: #32994. Could you please test again with that version and report back? Thanks!
